The Samourai Mk 1 is a compact and capable monohull sailboat, recognized for its blend of cruising comfort and surprising racing prowess. Designed by Michel Bigoin, with collaboration from Daniel Duvergie, this vessel was built jointly by Japan's New Japan Yacht Co. Ltd. and the French builder CNSO (Constructions Nautiques du Sud-Ouest). Launched in the late 1960s, the Samourai Mk 1 quickly gained recognition, notably securing a 3rd place finish at the prestigious 1968 International 1/4 Ton Cup (RORC), highlighting its competitive spirit within the quarter-tonner class.

The Samourai Mk 1 entered production in 1968 and continued to be built until 1970, with approximately 800 units produced across its run. Michel Bigoin, a designer known for various sailboats including larger models, conceived the Samourai Mk 1. While specific design philosophies for this particular model are not widely detailed, its performance in the 1/4 Ton Cup suggests a design focused on efficiency and speed within its rating rule, alongside practical cruising attributes. The builder, New Japan Yacht Co. Ltd., commenced operations in 1969 and has maintained a presence in the Japanese yachting market for over five decades, known for producing a variety of sailboat models. The collaboration with CNSO expanded the boat's reach, reflecting a common practice of international partnerships in boat building during this era. The Samourai line saw variations, including the Mk1 (7.4 meters) and the slightly larger Mk2 (7.6 meters), and it is noted that the Mk1 production featured many variations, indicating potential differences in configurations or outfitting over its short production span. The Samourai Mk 1 features a fin keel and a skeg-hung rudder, a common and effective underwater profile for its time, designed to offer a balance of performance and control. Its masthead sloop rig provides a straightforward and efficient sail plan.
Sailing Performance and Handling
Despite its compact size, the Samourai Mk 1 is characterized as a "moderate weight sailboat" that exhibits "reasonably good performance". Its design incorporates attributes that contribute to a stable and stiff sailing experience. This stability allows the boat to stand up well to a breeze, providing a confident motion even in challenging conditions. The Samourai Mk 1's performance capabilities were notably demonstrated by its 3rd place finish in the 1968 International 1/4 Ton Cup, a testament to its agility and speed as a racer. Owners can expect a boat that is responsive and handles predictably, making it suitable for both casual cruising and spirited club racing.
Accommodations and Layout
Given its length overall of just over 24 feet, the Samourai Mk 1 is designed to be a practical cabin cruiser, offering essential accommodations for overnight or weekend trips. While detailed interior layouts are not extensively documented in public records, typical arrangements for sailboats of this size often include a V-berth forward, a compact salon area that might convert into additional berths, and a basic galley and head. The design likely prioritizes functional space within a small footprint, aiming to provide sufficient comfort for its intended purpose as a coastal cruiser.
